For defense Rex has a solid, if not great, ARM of 2 red, mitigated a bit by his 6 hearts.

Rex is plods about with only 5 movement points. However, this lack of speed is made up for by a lengthy melee range of 3 squares. Which is nice because Rex is all about melee offensive actions.

Starting with a base STR of 2 red and 2 blue, Rex easily increases his offensive potential thanks to the ability Mob, which grants an additional +1 blue STR for every model with Mob in range with Rex's target.
